STREWTH: German publications have yet to issue an apology for publishing the pictures [GETTY / REUTERS]

And Germany’s best-selling tabloid mocked the royal again after being first to publish the embarrassing snap.

Kate’s behind was fully exposed when a blast of air from helicopter blades blew her dress up during last month’s royal tour of Australia.

The Sydney Daily Telegraph ignored calls for royal privacy and printed the picture under the headline “My bare lady: Derri-heir to the throne is fair game.”

Papers in the UK have declined to print the embarrassing snap of the Duchess of Cambridge, 32.

But German paper Bild, the first to show it, refused to apologise and mocked Prince William’s wife.

The paper said: “The Brits were a bit BUMmed that we showed Kate in that pose.

“Hey, don’t get too upset about it. We also have amazing backsides in this country and would like to show you now!”

Next to the article were snaps of 10 pert German backsides, including those of supermodels Claudia Schiffer, 43, above and right, Heidi Klum, 40, below, and Toni Garrn, 21, and tennis star Steffi Graf, 44.
